Chromospheric evaporation
WebThe transition energies between "gentle" and "explosive" evaporation regimes estimated from the observations ( erg cm -2 s -1) and derived from the models ( erg cm -2 s -1) are comparable with each other. The results illustrate relationships among the processes of chromospheric evaporation, the response of the colder layers, and the flare ... WebWe investigate the occurrence of slipping magnetic reconnection, chromospheric evaporation, and coronal loop dynamics in the 2014 September 10 X-class flare. …

WebJan 31, 1996 · Chromospheric evaporation has been detected in a large number of solar flares (e.g., Ding et al. 1996; Li & Ding 2004, 2011Falewicz et al. 2009;Raftery et al. 2009;Chen & Ding 2010;Veronig et al ...
WebNov 29, 2011 · We find clear evidence for typical chromospheric evaporation associated with small transient brightenings, using the data from the X-ray Telescope (XRT) onboard Hinode. We found 13 events, each having a pair of evaporation upflows arising almost symmetrically from both foot points of a magnetic loop. These facts strongly support the …
